IEEN' PENCIL.

Application filed February 8, 1926. Serial No. 86,873.

This invention, relating as indicated to a combination pen and pencil,refers more particularly to an lII'lPl'OV-OCl article of that classwherein the ink containing reservoir is of the self-filling type, andthe pencil of the expulsion type. An object ofthe invention is toprovide novel means for both effecting the control of the lead and forcompressing the ink containing reservoir. Another object of theinvention is to provide a combined pen and pencil which issimplc inconstruction and inexpensive in manufacture.

To the accomplishment of the foregoing and related ends, saidinvention,then consists of the means'hereinafter fully described and particularlypointed out in the claims.

The annexed drawing and the following description set forth in detailcertain mecha nism embodying the invention, such disclosed meansconstituting, however, but one of various mechanical forms in which theprincipl of the invention ma be used.-

In said annexed rawing:

Fig. 1 is an elevational view of the present novel device; Fig. 2 is acentral longitudinal section through the same; and Figs. 3 and 4 aresectional views taken on lines 3-3 and H of Fig. 2 respectively. I

The illustrated embodiment of my invention consists of a cylindricaltube constructed of two parts and 11 secured together at their adjacentedges by a cylindrical spacer 12. This spacer 12 has provided at itsends threads 13 and 14 which engage respectively with internal threads15 and 16 011 the adjacent ends of sections 10 and 11. Positioned at theouter end of section 10 is a fountain pen 17 which may be of anyconventional feed piece 18 are secured in the bore of said bushing 21.The other end of the device may also beprovided with threads 23 to whichthe cap may be secured when the device is being used as a fountain pen.in this cap member 20, in a recess at its outer end 24-, is provided aneraser 25.

To the inner reduced end of the bushing 21 within the section 10 issecured the open end 26 of an ink containing sack or reservoir 27, thesame being here. shown as a compressible corrugated rubber member whichmay be compressed longitudinally by pressure applied to its closed end28. In the filling operation of the present device certain mechanism, aswill appear hereinafter, is provided to exert a longitudinal pressure onthe end 28 whereby the air is exhausted from the ink containing sack 27.When such pressure is relieved the inherent resilience of the sack 27will tend to restore the same to its normal extended position and thusdraw in a supply of ink through the usual hole at the outer end of thepen 17 and through the hole 19.

As stated, the section 11 of the present combined pen and pencil devicecarries at its outer end, certain mechanism for containing and feedingpencil lead. This end 30, shown in Fig. 2, is formed conical and has acentral longitudinal opening 81 therethrough which is of proper size toaccommodate a pencil lead 32. Permanently secured to the end 30 ofsection 11 is an inwardly extending cylindrical tube 33 which serves isan inp nor support and guide for the lead as well as a guide for thelead propelling mechanism. A spacer 34 may be employed between such tube33 and the inner periphery of thecy-lindrical section 11 to strengthenthe entire. lcad containing structure.

As will be seen from an inspection of Fig. 2, the cylindrical spacer 12is of sutticient length to provide an annular space at its outer surfacebetween the respective ends of sections 10 and 11 when secured to saidtwo latter members. I propose to mount in such space a revolvable sleeve37 which is confined from longitudinal movement by engagement with theends of sections 10 and 11. On the interior of this sleeve 37 areprovided screw one leg 40 of a U-shaped member 41 which is utilized bothto expel the lead through the tube 33. and to compress the inkcontaining sack 27. The leg 40 has provided at its outer surface, rackteeth 42 which engage with the internal threads 38 of the revolublesleeve 37. Itwill be obvious that any rotation given to the sleeve 37will impart reciprocatory movement to the U-shaped member 41.

facilitate the manual operation thereof.

The connecting portion 43 of the U-shaped member 41 is positionedadjacent the end 28 er projection 47 fitting within the interior of,

of the ink sack and has a projecting lug 44 thereon disposed centrallyof the interior of section 10 adapted to contact with a disc 45 slidablymounted withinthe section 10 at the closed end of the sack.

, The other end or leg 46 of the U-shaped member 41 is extended parallelwith the leg 40 and is reduced in size to provide a plunge the tube 33.This plunger end 47 is adapted to engage with the inner end of the lead32 and as the member 41 is moved to the left of Fig. 2 through actuationof the sleeve 37, such plunger will force'the lead through the outerconical end 30. I

It will be apparent from the foregoing that I have accomplished theobjects primarily stated and that I have provided a new and improvedcombined pen and pencil which is simple in operation and which may beinexpensively manufactured and assembled. The mechanism provided forejecting the pencil lead is'so designed that it may be utilized forcompressing the ink containing sack; I am aware that there are manypatents relating to combined pen/and pencil devices. but in none of themis found the improved feature of providing a single .mechanism which isadapted -to serve both as a self-filling device for the ink reservoirand as means for expelling the pencil lead, b

Other modes of applying the principle of my invention may be employedinstead of the one explained, change being made as regards the mechanismherein disclosed, provided the means stated by any of the followingclaims or the equivalent of such stated means be employed.

'I therefore particularly point out and distinctly claim as myinvention 1. A device of the character described comprising a two-partcylindrical tube, a spacer securing said parts together, a fountain penin the outer end of one part, a lead guide in the outer end of the otherpart, a compressible ink sack mounted within said tube and The outersurface of the sleeve 37 may be knurledto connected to said pen, arotatable sleeve mounted on said tube, and connections actuated from therotation of said sleeve for compressing saidsack and for expelling leadthrough said guide.

' 2. A device of the character described com-- prising a two-partcylindrical tube, means for securing the adjacent ends of said parts inspaced relation,-a lead guide mountedin one of said parts, a fountainpen mounted in the other part, an ink sack connected to said pen,machanism for expelling lead from said guide, and means mounted betweenthe ends of said cylindrical parts for actuating said mechanism and forcompressing said sack.
